Hi Team,

What's the meaning of Timing input signal in below picture? And what's the exact value of tsu and th here? Pls help us, customer is asking. Thanks.

That graph is copied into all datasheets, and so shows more parameters than most devices actually have.

This device does not have a timing input. Ignore the setup/hold times.

Hey Stanley,

Clemens is correct. As note H mentions, all waveforms aren't applicable to all devices. They can ignore this one.

Thanks,
Rami

Hi Rami,

Adding another question here. Customer found some glitch amplitude is higher than high-level input voltage threshold, but our IC didn't turn high from low level. So is there any glitch free function in our IC, which requires sustained time here?

Best,

Stanley

Hi Stanley,

Can you share an oscilloscope shot of the input and output for what you are describing?
